New Compact Caged Ball Screw SDA
Achieve a slim nut with a new circulation system.
Compact Caged Ball Screw model SDA responds to high-speed application at 5,000 min -1 (maximum DN value: 130,000) and realizes low noise, comfortable running sound and long-term maintenance-free operation.
Slim nut with a new circulation system: Use of a newly developed end cap and R piece achieves an ideal ball-circulation structure and significant downsizing of product. The nut dimensions are compliant with a DIN standard (DIN69051)
Superb high-speed response: Use of a newly developed end cap and R piece achieves an ideal ball-circulation structure. This enables SDA to perform high-speed operation at 5000 min-1 (maximum DN value:130,000) approximately twice the previous model.
Low noise, comfortable running sound: Use of a ball cage eliminates collision noise between balls and ensures comfortable running sound. In addition, an ideal circulation consisting of a newly developed end cap and R piece further reduces noise.
Long-term maintenance-free operation: Use of a ball cage enables the formation of a grease pocket to increase grease retention, achieving long-term maintenance-free operation.
